Click on the green flag. The first side drawn is 250 steps in length. The second side drawn is 200 steps in length. The mouse turns left through a random angle = 90 through 135 degrees and draws the third side. The length of the third side is reported. This length is then tested against 250 and 200 to determine if the triangle has three unequal sides and is therefore scalene.
In Bloom's Taxonomy of Educational Objectives, a test of a learner's 'comprehension' of a concept is the ability of the learner to 'rephrase’ or ‘restate' the concept in as many different ways as possible. For several years I have been interested in using standard mathematics curriculum as a source of computer coding exercises in which students ‘rephrase’ math concepts. Geometry is an especially rich source for computer coding projects. In this document we use computer code to explore the scalene triangle concept.
